查询词典 pre-estimation

On the basis of theoretical analysis of target diffusion in range-velocity resolution cell, the array signal covariance matrix and noise covariance matrix are estimated from some different cells respectively. The processing results from experimental data in onshore HFSWR with Minimum Variance Distortionless Respose, MUltiple SIgnal Classification and pre-whiten MUSIC respectively show that super-resolution methods can provide better resolution than CBF.

鉴于 HFSWR 工作波长较长、常规波束形成角分辨力较差的缺点，基于目标在距离—多普勒平面分布的理论分析，本文利用相邻距离、多普勒频率单元信号估计阵列协方差阵，并分别利用 MVDR 、 MUSIC 、预白化 MUSIC 方法进行超分辩处理，实测的合作飞机目标数据处理结果表明超分辩方法能明显提高阵列角度分辨力。
